4. The method of claim 1 , wherein the request comprises a media access control (MAC) address of the computer device and a request for the list of the available VLANs at the port.

5. The method of claim 1 , wherein the acknowledgement further comprises a number of the port.

6. The method of claim 1 , wherein a user determines the one of the VLANs configured for the computer device.

7. A computer program product for dynamic discovery and assignment of virtual local area networks (VLANs), the computer program product comprising a computer readable hardware storage device having program code embodied therewith, the program code executable to: receive, by a network switch, a request for a VLAN configuration, from a computer device connecting to a port of the network switch; retrieve, by the network switch, a list of available VLANs at the port; determine, by the network switch, whether respective ones of the available VLANs are configured for the computer device; determine, by the network switch, to include the respective ones of the available VLANs in an acknowledgement, in response to determining that the respective ones of the available VLANs are configured for the computer device; form, by the network switch, the acknowledgement to the request, the acknowledgement comprising a list of VLANs configured for the computer device, in response to determining that the respective ones of the available VLANs are not configured for the computer device and in response to determining that the respective ones of the available VLANs are checked; send, by the network switch, the acknowledgement to the computer device; wherein the acknowledgement is used to determine one of the VLANs configured for the computer device, the one of the VLANs configured for the computer device is tagged by the computer device to an adapter of the computer device, and the computer device is connected to the one of the VLANs configured for the computer device; and wherein the computer device is connected to the port of the network switch, the port of the network switch is configured to allow access to the VLANs, and the port of the network switch contains the list of the available VLANs at the port.

8. The computer program product of claim 7 , wherein the program code is further executable to: send, by the computer device, the request for VLAN configuration to the network switch; receive, by the computer device, the acknowledgement from the network switch; determine, by the computer device, the one of the VLANs configured for the computer device; tag, by the computer device, the one of the VLANs configured for the computer device to the adapter of the computer device; and connect, by the computer device, to the one of the VLANs configured for the computer device.

9. The computer program product of claim 7 , wherein the computer device is a computer system capable of executing computer program instructions and communicating with another computer system through a network.

10. The computer program product of claim 7 , wherein the request comprises a media access control (MAC) address of the computer device and a request for the list of the available VLANs at the port.

11. The computer program product of claim 7 , wherein the acknowledgement further comprises a number of the port.

12. The computer program product of claim 7 , wherein a user determines the one of the VLANs configured for the computer device.

13. A computer system for dynamic discovery and assignment of virtual local area networks (VLANs), the computer system comprising: one or more processors, one or more computer-readable hardware storage devices, and program instructions stored on at least one of the one or more computer-readable hardware storage devices for execution by at least one of the one or more processors, the program instructions executable to: receive, by a network switch, a request for a VLAN configuration, from a computer device connecting to a port of the network switch; retrieve, by the network switch, a list of available VLANs at the port; determine, by the network switch, whether respective ones of the available VLANs are configured for the computer device; determine, by the network switch, to include the respective ones of the available VLANs in an acknowledgement, in response to determining that the respective ones of the available VLANs are configured for the computer device; form, by the network switch, the acknowledgement to the request, the acknowledgement comprising a list of VLANs configured for the computer device in response to determining that the respective ones of the available VLANs are not configured for the computer device and in response to determining that the respective ones of the available VLANs are checked; send, by the network switch, the acknowledgement to the computer device; wherein the acknowledgement is used to determine one of the VLANs configured for the computer device, the one of the VLANs configured for the computer device is tagged by the computer device to an adapter of the computer device, and the computer device is connected to the one of the VLANs configured for the computer device; and wherein the computer device is connected to the port of the network switch, the port of the network switch is configured to allow access to the VLANs, and the port of the network switch contains the list of the available VLANs at the port.
